## Resource

Lucas and Luna dive into the technical decisions behind Airbnb's 2024 search architecture overhaul. With 8 million active listings and billions of queries daily, Airbnb moved from a monolithic Elasticsearch cluster to a multi-tiered retrieval pipeline combining inverted indexes, vector embeddings, and real-time ranking. They explore why Airbnb chose to build custom microservices over managed solutions, how they reduced median search latency by 40 percent without sacrificing relevance, and the operational headaches of migrating 500-plus engineers to a new query language. A concrete look at search infrastructure at planetary scale. #Airbnb #SearchArchitecture #Elasticsearch #VectorSearch #Microservices #LatencyOptimization #EngineeringLeadership #TechInfrastructure #BusinessAndTechnology #CTO #SystemDesign #Scalability #MachineLearning #RealTimeRanking #DataEngineering #MigrationStrategy #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
